CDUPLING.

Application led September 10, 1921.' Serial No'. 499,755;

To @ZZ whom t may concer/n:

Be it known that we, JOHN ARTHUR Wnrs and Fnnnnnron I. Knoten, both citizens of the United States, residing, respectively, in the borough of Manhattan, city, county, and State of New York.y and Carlton Hill, county of Bergen, and State of New Jersey, have invented an improvement in Couplings, of which the following is a specilication. f

This invention relates to a coupling and more particularly to that type of coupling which is shown and described in copending application, Serial No. 362,076, iled February'28, 1920, by John Arthur YWeis, one of the inventors herein, and yadapted to be connected to the end of a hose for joining adjacent sections of hose to one another, or a hose section to any suitable outlet. The hose coupling made in accordance with the present invention, like that shown in the application aforesaid, is constructed to engage the outer portion of the hose irrespective of variations in its diameter, and in the present case the invention still more particularlyT relates'to a construction in which the inner section of the hose is also engaged and clamped so as to be adapted for use in con# nection with metal lined hose and with any type ofhose where the hose is'to carry an excessive pressure in order to insure an absolutely tight joint between the ends of theY hose and the coupling. f

ln accordance with the present invention, therefore, the construction preferably comn prises a pipe section or body member adapted to receive one end of a section of hose together with clamp members adapted to engage the hose eX-teriorly thereof so as to clamp the same against the body member, and devices for also engaging an inner portion of the hose to clamp the same either between the body member or the clamp members, there being means provided for either separately or simultaneously operating the said clamp members, and interiorly engaging devices for making a tight joint as will be hereinafter more particularly derr scribed.

In the drawing:

Fig l is an elevation'ofa coupling madev Fig. 2 is a central longitudinal cross section of the same.

Fig. 3 is a central longitudinal cross section of another form of the invention.

Fig. i is a view similar to Fig. 3 showing the parts in this form of the invention in ya different position; Y

Fig. 5 cross section showing another form of the invention, and

Fig. 6 is a view similar to Fig. 5 showing still another form of the invention.

Referringl to the drawings and particw larly to the form of the invention' shown in Figs. l and 2, the coupling made in accordance with the presentinvention comprises a tubular pipe or body member l0 adapted at one end to receive a section of' hose, that is to fit into the end of the hose so that the outer diameter of the body member is substantially the same as the inner diameterof the hose, and as illustrated in these and other figures of the drawing, the hose is the metallic lined type,` the outer fabric or other 'covering of the hose being indicated at l1. while the inner metallic section of the hose is indicatedY at l2. The opposite end of the tubular body member 10 as illustrated in these figures is provided witha flange or head 13 adapted to receive a coupling- 14 in which there is also received the end l5 of an adjacent section of pipe with an intermediate gasket or washer 16 in orderto make a tight joint between these parts. y

A. portion of the outer surface of the body member l() adjacent 4the head end thereof is screw threaded as'indicated at 17 to receive av nut 1S which. as illustrated in these iigures, isprovided with a tubular sleeve extension 19 adapted to extend over a portion of the tubular body member 10 and to lie parallel therewith. A. portion of the outer surface of the tubular sleeve extension 19 is screw threaded as indicated at 20 to receive a wedge nut 2l and a lock nut 22. .'Also on the end of the tubular Vbody member, we provide a collar 23 which, as illustrated in these ligures. is provided'with a wedge extension 24. This collar 23 and its wedge eX- tension 24l`are adapted to lit and slide on the reduced end 25 of the tubular body mem ber 1 0 and to abut against a Yshoulder 2d is a partial central longitudinalr therein to limit and determinethe movement in one direction of thecollar 23 so as to prevent the collar and ltswedge eX- tension from being moved beyond this pomade kof any suitable material, andas illus` f the clamp` member. Also as illustrated, theA trated this may be provided adjacent Yits apex end with a packing ring 28er band to maintain the inner end of the wedge packing 27 in position; Y

VThe members for engaging the outer surface of the hose include a plurality of arms each comprisinga lbody portion 29 and an arm or extension leading therefrom and preferably at an angle thereto. rlhe body member of each of these clamps is indicated at 29 and the arm vthereof at 30.. YVEachof these clamp 'members .isk provided with a recess in its exterior surfaceY at a position approximately midway of its length and when in place each one of these clamp menr bers tits within a ring 31 which is adapted to lie in the recess inthe kouter surface of clampV members in the inner surface of the body portion thereof may beprovided with ribs or projections-32 for engaging more securely the outerfsurface of theyhose. n this form ofthe invention, as will now be apparent, after the hose has been fitted to the lend ofthe tubular body member the Wedgev nut 21 Ymay be turned a predetermined extent to cause the inclinedV surface thereof to engagethe upper portions of the arms 30 to'force the Vbody portions of the Vclamp members into the outer'surfacef'of the Y hose so as to engage the same and fix it in clamp members and the tubular body lmem-V A ber 10. The nut 18 may then be turned suffiposition between these body portions of the oiently lto cause the extension' sleeve 19 to 'bear against the collar 23 and force the wedge extension 24 thereof into the conical packing 27 to force the same outwardlyy and clamp the outer section of the hose between this wedge .extension 24 arfd the conical packing 27 and the body portions .29 of the .clamp members. "These various parts may be thus moved-suiiiciently Vfar to insure an absolutelyrtight jointbetween the hose and theengaging membersv of 'the clamp, ity being appreciated that the clamp members maybe employed to engagethe hose irrespective of its outer diameter and that when the parts n are in placethe lock nut22 may beturnedV down against the wedge nut 21 yto secure'the sametherein.y In this form of the invention, as vwill be understood',the operation ofthe clampmembers'to engage the outer portions,`

" of the hose is independent of the operation and adjustment of the parts for'engagmg the inner section of the hose.

`Referring to Figs. 3 and 4, it will .be seen thatwemay dispense wwith the conical. orY wedge shaped packing member '27 and also adapted to be forced into the metal lining'- of the hose to fillthe spaces between the same at the-extremity thereof so as to make avtight jointf In this structure, 'as in that i shownY in Figs. 1 and 2, the clamp members are actuated by the wedge nut 21 so as to engage the outer surface 'of' the hose with the ring 31 acting as a' fulcrum and the parts in this position are illustrated in Fig. 3. The nut 22 may then be turned vto force the upper extremity of the tubular sleeve eX- l tension19 against the collar or ring 33 which in turn forces the wedgeA shaped member 34 into the metallic hose lining until the-parts 'Y assume the position shown inFig. 4, when,

as will be understood, the wedge nut 21 may Y be further turned, if necessary, and the lock nut 22 caused to secure lthe parts :in posi- .'tion. Also in thisgform of the invention,

the screw threaded end ofthe body member 10 is adapted to be turned down inthe coupling member '35* with an Vintervening washer or gasket 36 to maire a tight joint between these parts. Y

By reference to Fig. 5, it will also be seen that in this form of the invention, the nut 18 and its tubular 'sleeve extensionV 19 may be Vdispensed withand the wedge nut 21 placed directly on a screw threaded portion of the'outer surface of the body member 1()y asis illustratedv in the copendingapplication to which reference has hereinbefore been made. In this structure, we employ,y a sleeve membery 37 adapted at one end to contact with the inner extremity of the wedge nut land at its`other Y i end with the ivedgemember 39 so that the hose may be clamped both interiorly and eX- Y teriorly by the sameor simultaneous operaf tion-that is to say, and as will be apparent, when the wedge nut is turned on the screw threaded surface of the bodyV member'to engage the arms of the clamps the body portions Vof the clamps will engage the outer surface of the'hose andthe wedge nut will force the sleeveV 37 against thefwedge`39 Yso as to force the same to .position yin the'metal lin# ing of the hose atlthesame time the hose is clamped between the body portions of the K4clamp members and the tubular body member of the coupling.

By reference to Fig. V6,it,will.,furthermore Y be Vseen that in some instances instead of neeneee forcing the metal lining or the inner' portion tween the inner wedge member and the body portions of the clamp members, kwe may force a suitable ypacking r3 between the end of the metal lining and the adjacent surface of the body member by a crown Lil the inner end i2 of? which then lies adjacent the extremity of the hose, the crown il being carried by a sleeve 40 with which it may be integral or otherwise. i

iVhile we have herein shown and described various forms of carrying out the invention to grip a hose both exteriorly and interiorly between the parts of a coupling,

it will be understood that other equivalent forms may be employed without departing from the nature and spirit of this invention, forr example the clamping members might be omitted and their equivalent parts employed, and various forms of inner packing parts might also be used in connection with the devices for forcing them to place.
